Answer: The reason weight for average adult is 530N
Explanation: The clearly see this answer, let's convert this weight to kg using F=mg
530=m×9.8
g is a constant of 9.8m/s2
We divide both sides by 9.8 to get
54kg then this weight is reasonable for an average adult.
Answer:
Thrust is the force acting normally to a surface. So, Thrust = 1200 N. And , Pressure = Thrust / Area. = 1200 / 0.001. = ...
Explanation:
this right like me
Answer:
25m/s²
Explanation:
Using one of the equations of motion.
v² = u²+2as where
v is the final velocity of the astronaut
u is his initial velocity
a = -g (the acceleration will be acceleration due to gravity since he is acting under the influence of gravity. The value is negative because the astronaut jumps up to a particular height)
s = H = total height covered
The equation will then become;
v² = u²-2gH
Given
u = 60m/s
v = 0m/s
g = ?
H = 72m
Substituting the given value into the equation;
0² = 60²-2g(72)
0 = 3600-144g
-3600 = -144g
g = -3600/-144
g = 25m/s²
The magnitude of his acceleration due to gravity on the planet is 25m/s²
